110 THE FOSSIL COKALS AND ALCYONAEIA OF SIND. 



Isis, sp. 2. 



The joint is moderately long, slender, exceedingly delicately and straightly grooved, 

 faintly enlarged at the ends, and the joint-surface is concave. This form is allied to 

 Isis Peloritana, Seg. op. cit. p. 16, from Messina, in the uppermost Miocene strata. 



Height of specimen -^ inch ; breadth not quite -yq inch. 



Plate XXVm. Fig. 11. A joint: natural size. 



Isis, sp. 3. 



The joints are long, well and pointedly convex at their ends, faintly yet decidedly 

 grooved in a straight direction in some places and oblique in others. Small abortive 

 branches are noticed, and the grooving is only just continued over the edge of the 

 upper and lower surfaces. The ridges branch occasionally, and the body is slightly 

 broader at the joint-ends than in the middle. 



Length of joint ^o inch; breadth -^o inch. 



Another specimen is shorter, but shows the peculiarities of the species.

These Isidine remains give a very late facies to the fossils of the Gaj or Miocene 

 series of Sind.
